I Application-filed June a,

.To (ZZZ whom it may'concem Beit-gk-nownwthat I, EDSVARD DnarnRLn, a citizen of theUnited States, and resident of borough of' Manhattan, in the city, county, and State-of New York, havevinvented certain new and useful Improvements in Vibratory Tools,- is aspecifiication. a V

This 4 invention relates to vibratory tools applicable for various purposes, and, by way of example, intended by me .for'use by in. manipulating:- the-settings for precious stones, etc. r

In thea'rt of setting of, which the following prongs, tines or;sockets may have just the may bewrendered both securecand symmetrical, whereby'the jewel may befirm-ly held against displacement, and also that'the appearance' of the :se'tting'may have a pleasing and artistic effect. When the pressure of a setting tool'is applied by manual means, as is the present practice, the most skillful op erator sometimes fails, either in according full security to the anchorage, or in attain ing .artistic symmetry therein. This is due to the fact that the hand applied pressure is not susceptible of being exerted under complete control. 1

Therefore my invention consists in the provision of a tool which is capable, through, mechanical means, of vibrating under the influence of a succession of internal impacts, that are created by afiying or free piston in response to alternately applied air pressure and suction forces. I

This device consists of a hollow cylinder having at one end means for fitting a setting tool. thereto, and at its other end connecting with a flexible tube, whereby, with the aid of suitable pumping means, air pressure and suction are alternately applied to the hollow cylinder, in quick succession. The hollow cylinder contains a free piston which under an air pressure impulse is thrown against the tool engaging end of the cylinder, and under the succeeding'suction impulse is drawn to the opposite end of the cylinder, where it meets a cushion to absorb the shock of its rearward movement,1so that the vibratory shocks will be unidirectional, exerting force for impacting only in a forward direction relatively to the tool.

The pump cylinder 1 has at its outer end a nozzle 12, adapted for engage ment by a flexible tube 18', so that the air into tube 18, and so that said plunger, in its outward strokes, may exert suction influence upon said tube. The opposite end of tube 13 is adapted for connection with a threaded end nozzle portion 14 of a hollow cylinder15, in which opposite end portion is interiorly threaded, as at .17, 'to receive the threaded portion 18 of a tool holder 19, said tool holder having p a socket 20 for the reception of a'tool 21, 95 which is to be secured in said holder as by means of a set screw 22. p The interior of cylinder 15 is exposed to the atmosphere, at its end near the tool holder, as by the ports 23, 'and,.at its end 1 00 ;v I is a free piston 16. Said cylinder 15,. at its against the abutting end of tool holder 19, which comprises the tube closure at its forward end, thereby imparting a forward jar or shock to said cylinder and the tool which is a rigid element thereof, and the reaction or suction strokes of the plunger 2 will draw back the piston into contact with the spring cushion 24:, which latter will absorb the jar orshock that would otherwise be created by the piston in its reactive movement.

Therefore, according to the speed with which the plunger is driven by the motor, and the consequent energy ofthe piston operative impacts. so will the tool develop suitable vibratory force.

When used as a jewellers setting tool, the tool 21 is grasped between the fingers and thumb of the operators hand, and its point is directed against the prong, tine or socket to be formed or shaped upon or about the jewel, whereupon the succession of forward impacts communicated to the device, in the reciprocatory action of the free piston, will permit the application of a regulated desirable degree of vibratory pressure.

Motor speed regulating means, here shown as a rheostat 25, actuatedby foot control means 26, serves to Vary the rate of rotor revolution and thereby governs the rate of pump operation.

It will be appreciated that the herein described device constitutes a manually directed tool, which permits it to beapplied to the setting at those points where pressure is to be employed, but the artizan is not required to exert manual pressure in bending over the setting portions to bind formed more expeditiously with this me-- chanically actuated tool than with the usual form of hand setting tool,

Variations within the spirit and scope of my said invention are equally comprehended herein.

I claim A pressure applying device to be manually held and directed comprising a hollow cylinder, a tool fixedly carried thereby, a free piston within said cylinder, and pneumatic means for reciprocating the piston throughout the cylinder extent to vibrate the device.

Signed at the borough of Manhattan, in the city, county, and State of New York this 31st day of May, A. D. 1921.
